Am I missing something else here?
This is supposed
to be wired up via the RandR 1.1 protocol, which you can force xrandr to query by passing the --q1 option. Unfortunately, that's apparently not wired up properly right now so you current have to use nvidia-settings -a CurrentMetaMode to modify the current MetaMode, or xvidtune -next to cycle through them.
A future driver release should list the MetaModes through the RandR 1.1 interface the way 295.* and earlier did.
